Distribution: So far known from the central part of Sula wesi (especially from localities near the border between Sulawesi Selatan and Sulawesi Tengah, Tanah Toraja) and Buton (= Butung) island (see Map). Ecological data available: Preimaginal stages and lar val foodplants are unknown. — Specimens were found between 1000 m and 1800 m elevation (insofar as altitu Map: Localities of Eupterote (E.) celebica on Sulawesi and Buton.
